以应变综合结构势作为土结构性参数,对真三轴条件下的非饱和黄土的结构变化特性进行了初步探讨,分析结果表明:真三轴试验条件下非饱和黄土的结构性参数曲线与常规三轴试验条件下黄土结构性参数曲线具有相同的线形和变化特征;中主应力变化对黄土结构强度具有显著影响;真三轴试验条件下,周围压力和含水率对黄土结构性参数的影响规律同于它对常规三轴试验条件下黄土结构性参数的影响。
Taking the strain synthetic structure potential as soil structure parameter, the structural change characteristics of unsaturated loess in true triaxial condition are discussed. The results show that the structural parameter curves of unsaturated loess under true triaxial test are similar to those of conventional Under the triaxial test conditions, the structural parameter curves of the loess have the same linear and changing characteristics; the change of the middle main stress has a significant effect on the structural strength of the loess; under the true triaxial test conditions, the influence law of the surrounding pressure and water content on the structural parameters of the loess Same as it affects the structural parameters of loess in the conventional triaxial test.
